65-107 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 640nm
The 65-107 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 640nm, making it ideal for applications that require precise wavelength selection within this range.
The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 65-107'. This coating enhances the filter's durability, making it resistant to wear and tear, a crucial factor for components subjected to frequent handling or rigorous use.
The filter's geometry is defined by a diameter of 12.5 mm and a thickness of 3.5 mm. This thickness, denoted as 't=3.5 mm', contributes to the filter's overall structural integrity and stability.
The Bandpass Filter's physical data includes a cut-on wavelength of 635nm and a cut-off wavelength of 645nm. These values are crucial in determining the filter's passband, the range of wavelengths that the filter allows to pass through. The central wavelength (CWL) of the filter is 640nm, which is the wavelength at which the filter's transmittance is maximum.
The filter is designed in a Thin Lens shape, which is a common configuration for optical components. This shape allows for easy integration into various optical systems.
